feat(automations): trigger→condition→action engine with cooldown + dry-run
- AutomationEngine: state_change + time triggers, cooldown debounce, dry-run
logs instead of switching (H5), actions switch via DeviceCommandService
(source=automation, audited H1) or notify via log.
- EvaluateAutomations: queued listener on DeviceStateChanged (keeps ingest
fast, H2). automations:tick command scheduled every minute for time rules.
- CreateAutomation modal (wire-elements) wired to Automations index; DE/EN
keys (R16). dry_run column migration + model cast.
- AutomationTest: 6 cases (trigger match, mismatch, cooldown, dry-run,
time tick, disabled). Full suite 23 green; 11/11 tabs clean (R12).
